Thanks to annarchon for sharing that the drive is cheaper at CentreCom at $78. If you add a low price item such as thermal paste or a short Cat6 cable ($2.50), you'll be able to get it over the $79 free metro shipping threshold. However, if you are outside the free shipping area, then the Amazon AU deal is still pretty good.
This is from Amazon AU locally, so should be delivered faster than the Amazon UK listing recently (and slightly cheaper too). Noted that it isn't that much different from current local market prices of other retailers, but it's significant enough for this category and price point, especially after one considers shipping cost.
Pretty good price for a reliable SATA SSD with DRAM, although if you aren't needing one urgently, there's a good chance you'll see the fantastic price of $79 (delivered) for MX500 500GB in the near future. There aren't much practical difference for general users between different brands of reliable mainstream SSDs, so go for whatever is the cheapest.
Personally I see reliable SSDs are what Anandtech described as follows (https://www.anandtech.com/show/9799/best-ssds):
We consider mainstream SATA SSDs to be those that use TLC NAND and have DRAM buffers. These offer performance and reliability that's a step above budget models with DRAMless controllers or QLC NAND (or both).
Pretty much they are the Samsung EVOs, WD Blue 3D/Sandisk Ultra 3D, and MX500 (SK Hynix isn't that common here yet?).
